| This research suggests that Ascocotyle infection has a minimal morphological effect on the mummichog heart. |
| The atlantic tomcod is one of the predators here, preying on such species as rainbow smelt and mummichog. |
| They prey upon the rainbow smelt, golden shiner, common shiner, creek chub, and mummichog, among others. |
| Under ambient winter temperatures with daily feeding, mortality did not occur for mummichog and sheepshead minnow, was low for winter flounder and high for silver perch. |
| The seasonal marine migrant Atlantic silverside and resident mummichog were most abundant in the lower reach. |
| Common fish species in the area include atlantic tomcod, mummichog, redfish, herring, silver hake, Greenland halibut, and the dangerously overfished northern cod. |
